Read standard output from a .exe libusb0 based

[dariogi888]

Hi All,

I'd like to receive your support. Currently I have a simple .exe based on libusb0_x86.dll, that monitors a value's sensor. Since I'm not able to use the libusb0.dll in Labview, I'm thinking to interface directly with the .exe using for example the "System execute.vi" but I don't know if it's the correct way. At the moment I'm able to launch the .exe from labview, but I don't know how read in labview the outputs showed in the .exe.

Do you have any kind of suggests?

Thanks

Why can you not use the call library function node to access the DLL from LabVIEW? What did you use to create your .exe?

I didn't create a .exe. It was developed by third part.

I'm not able to call the libusb.dll because I don't have details about the ddl's functions.

If the exe was created with LabVIEW, you may be able to use some property nodes (VI Server) to access control and indicator values. If the exe was not created with LabVIEW, you could try taking a screenshot and using optical character recognition to get the value out, but that may not be too reliable.
